A Catalyst article about practical chemistry experiments and the risks involved. The article helps in identifying, assessing and controlling the risks involved, it also includes a guide to the warning signs, labels and symbols used in laboratories.

This article is from Catalyst: GCSE Science Review 2004,...

Professor Saiful Islam is a chemist who never wears a white lab coat. Rather than conduct experiments in laboratories, he uses the world's most powerful computers to produce computer models of the inner, 'atomic' structure of materials used in 'green' energy applications, from the lithium ion rechargeable batteries...

A Catalyst article about why human beings need salt (sodium chloride) in their diets to survive, but too much can be toxic. Where does salt come from, and what is it used for? This article looks at salt extraction and mining in England, the domestic and industrial uses of salt as well as its molecular structure....

What happens when we add a pinch of salt to a lump of ice? This activity provides a chance for children to investigate the phenomenon and to find out how it relates to their everyday lives.

Salters' Science books differed from the typical textbooks at the time of publication. There were four books for the double-award science course: two for Year 10 and two for Year 11. Each book included chapters related to five or six of the modules in the course.

The books were designed to reflect to aims of...

Salters' Science was a complete teaching programme to provide an applications-led approach to double award science at Key Stage Four. It was followed by 'Science Focus', a Key Stage Three programme to illustrate a similar approach to teaching and learning in science....

The Salters' Science Focus course provides a rich variety of different types of learning activities, which are described in sufficient detail to be taken and adapted into any Key Stage Three scheme of work. This guide covers Year Seven of the course Science Focus: the...

The Science Focus: the Salters’ Approach course provides a rich variety of different types of learning activities, which are described in sufficient detail to be taken and adapted into any Key Stage Three scheme of work. This guide covers Year Eight of the course, suggesting a scheme of work for each of nine units...

The Salters’ double award science course included 12 modules for Year Ten. Each module relates to materials, phenomena or ideas which would be familiar to students or of value in their everyday lives. These starting points illustrate scientific principles in action, creating an applications-led course of study. By...

The Salters’ double award science course included 11 modules for Year 11. Each module relates to materials, phenomena or ideas which would be familiar to students or of value in their everyday lives. These starting points illustrated scientific principles in action,...

The Salters’ science courses were developed in the late 1980’s and early 1990’s to provide a complete balanced course in science for Key Stages Three and Four (ages 11-16). This section of the STEM elibrary covers the Key Stage Three materials. The timing of the development allowed a particularly close relationship...

Salt water is denser than freshwater. That is why we float so much more easily in the sea than in a lake or a swimming pool. An object will float if it is less dense than the water surrounding it. Therefore, things float easier in salt water as it is denser than freshwater. This is particularly evident in the Dead...

In this activity aimed at ages 9-10, children solve a problem faced by farmers in Mexico – ‘How to grow strong, healthy plants, that can survive and thrive in difficult conditions’. ...

This activity allows pupils to learn how to analyse samples on Mars. Students are given the opportunity to use targeted information in areas of astrobiology and geology, to work out what their rovers have found on Mars surface and to think like a geologist as they investigate stratigraphy (layers or rocks) using...
